AWS Mainframe Modernization now supports connectivity over Internet Protocol version 6 (IPv6)

AWS Mainframe Modernization introduces dual stack support for the managed runtime environments, enabling you to connect using Internet Protocol Version 6 (IPv6), Internet Protocol Version 4 (IPv4), or dual stack clients.

The urgency to transition to Internet Protocol version 6 (IPv6) is driven by the continued growth of internet, which is exhausting available Internet Protocol version 4 (IPv4) addresses. With simultaneous support for both IPv4 and IPv6 clients on AWS Mainframe Modernization runtime environments, you are able to gradually transition from IPv4 to IPv6 based systems and applications, without needing to switch all over at once. You can also continue to use IPv4 connections if you do not yet utilize IPv6.

There is no additional charge when you connect to AWS Mainframe Modernization using Internet Protocol Version 6 (IPv6) clients. Support for IPv6 is available in any AWS Region where AWS Mainframe Modernization managed runtime is already deployed.
